We love ya, and I cannot thank you enough. The support the entire entertainment community and music fans have shown is a testament to the love that country music embodies. This song is a God thing. My hope is that it reaches all who need to hear it. My son Jerry’s work on earth did not end with his passing. THANK YOU, everyone.”
